Handling Static–Sensitive Devices
Attention: Adapters, planars, diskette drives, and disk drives are sensitive to static
electricity discharge. These devices are wrapped in antistatic bags, as shown in this
illustration, to prevent this damage.
Take the following precautions:
If you have an antistatic wrist strap available, use it while handling the device.
Do not remove the device from the antistatic bag until you are ready to install the
device in the server.
With the device still in its antistatic bag, touch it to a metal frame of the system.
Grasp cards and boards by the edges. Hold drives by the frame. Avoid touching
the solder joints or pins.
If you need to lay the device down while it is out of the antistatic bag, lay it on
the antistatic bag. Before picking it up again, touch the antistatic bag and the
metal frame of the server at the same time.
Handle the devices carefully in order to prevent permanent damage.
